99% Pure copper
Made of high-strength and heat-resistant copper for durable use.
It has high safety and stable performance.
Strong corrosion resistance.
Its pointed end shaped like a needle that is suitable for crafted workmanship, for example, fit the alarm fob of a car, micro switch had popped off the small circuit board and the contacts for the micro switch are smaller than micro (smaller than a pin head), or soldering in a narrow space, revising the tin bridge emerging from chip soldering. It makes soldering work delicate and easier.
Easy to clean, use the sponge to polish the surface. Please do not leave them exposed to the air, better wrap them with tin. Don’t leave your iron tip running for hours and hours if you are not using it. This can make the tip get black oxide cover. (If you leave it on too long or run it too hot it will burn off the solder and go black.
